i bought this real time clock module:http://www.ebay.de/itm/261043197718?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

but i have problems to get it running, first of all like 90% of all libraries were pre 1.0 after changing the commands i still could not compile..then i found another library with an example that did compile but its still not working.

Could anyone please tell me where i could find the latest libraries and instructions?? :-/

and i would love just a simple example that shows me the current time and date of the clock.examples that did compile just show the same date and time over and over again, maybe thats intendet or not i dont know :-(

As only repeating output from serial i get from chronodot lib with example:2011/04/04 22:07:00and temp values.Time and other values r not changing at all :-(plz help

After connecting the backup battery the chip may power up with the clock disabled - one of the bits in one of the registers has to be set to enable the clock - so long as there is battery backup it will then keep running until you clear the bit again.

I dont remember the datasheet saying anything about guaranteed behaviour with no battery.

And I read "I didn't connect the battery" as "It wasn't connected", sorry.

Yes you need to program the device after removing/replacing the battery as all its state is all static RAM which needs power to work. The RAM starts up at random after backup power loss. I don't remember there being anyway to test for either no battery or that the battery has been replaced.
